The **ZWS150BAF-12-R** is a high-reliability, industrial-grade AC-DC power supply manufactured by TDK-Lambda. It is part of the ZWS-BAF series, known for its compact design, high efficiency, and convection cooling capabilities. --- ### ## Technical Specifications Below is a summary of the core electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Output Voltage** | 12V DC | | **Output Current** | 12.5A | | **Maximum Power** | 150W | | **Input Voltage Range** | 85 - 265V AC (Universal) or 120 - 370V DC | | **Efficiency** | ~88% (typical at 200VAC) | | **Cooling** | Convection (No fan required) | | **Operating Temp** | -10°C to +70°C (with derating) | --- ### ### Key Electronic Components & Features The "R" suffix and "BAF" designation indicate specific internal design choices: 1. **Active Power Factor Correction (PFC):** The unit utilizes an active PFC circuit to ensure compliance with IEC61000-3-2 standards. This reduces harmonic current emissions and improves energy efficiency. 2. **Remote ON/OFF Control (The "-R" Suffix):** The "R" in the model name indicates that this specific variant includes a **Remote ON/OFF** terminal. This allows an external signal to toggle the output without disconnecting the AC input. 3. **Electrolytic Capacitors:** TDK-Lambda uses high-temperature, long-life capacitors in this series to ensure a high MTBF (Mean Time Between Failures). 4. **Protection Circuitry:** * **Overcurrent Protection (OCP):** Constant current limiting with automatic recovery. * **Overvoltage Protection (OVP):** Shuts down the output if the voltage exceeds a safe threshold (approx. 13.8V - 16.8V). --- ### ### Physical Interface (Connector Type) The ZWS150BAF typically uses JST (Japan Solderless Terminal) connectors for its inputs and outputs to save space and ensure secure vibration-resistant connections. ```text Input Connector (CN1): JST B3P5-VH Output Connector (CN51): JST B8P-VH Remote ON/OFF (CNP1): JST B2B-XH-AM ``` --- ### ### Application Use Cases Due to its open-frame design and high reliability, this part is commonly used in: * **Industrial Automation:** Powering PLCs and sensors. * **Test and Measurement:** Low-noise power for laboratory equipment. * **Medical Equipment:** (Non-patient contact) due to its high isolation and safety certifications.
